I don't know about you. The car I'm driving is 9 years old and it is still going strong. I will likely keep it for another 3-4 years at least. Gadgets don't last this long. I'm afraid it might work wonder now but in a few years it is an eye sore every time I get into the car. I wouldn't buy car comes with this kind of crap. Give me bluetooth and auxiliary jack. I'm satisfied.
FB could sign up 19B users for $19B if they pay $1 per user when they use facebook messenger. I know what the entire population of the world. Who cares? The investors are all after the number of users. I don't think they care much about number of REAL people, do they?
Never say never. Their market share (iphone and various sizes of its cousin) are down and there is no way it will ever go back up. The next thing we know, iphone market share will be down to single digit. Of course the company will continue doing well for the years to come. Look at blackberry, their major break through was with RIM 950. It took them 12-15 years to collapse. The market is more competitive now. I'm betting Apple has at least 7-8 years of time left if they don't do anything -- i.e. we will continue seeing record profits year after year until the end its sudden death.
